At College Town Infant and Nursery School we follow the Letters and Sounds document. Letters and Sounds is divided into six phases, with each phase building on the skills and knowledge of previous learning. There are no big leaps in learning. Children have time to practise and rapidly expand their ability to read and spell words. They are also taught to read and spell ‘tricky words’, which are words with spellings that are unusual or that children have not yet been taught.
